The 2-year-old who was killed when a driver crashed into a crowd of people at Oklahoma State University’s homecoming parade is being remembered by those who loved him as a boy who was full of life.

“Nash was the symbol for love and joy,” the toddler’s father, Josh Lucas, told NBC News on Monday. “I lived for him and I’ll never stop loving my son.”

Nash’s teacher, Mercedes Kling, said she is heartbroken about the death of the boy who “was always funny.”

“Nash was the type of kid where you never knew what he was going to say,” Kling said. “I was always smiling at the things that he said.”

The 2-year-old was one of four victims to die after a woman accused of being under the influence plowed her car into the sidelines of OSU’s homecoming parade on Saturday. Three victims died at the scene, and Nash died later at the hospital.

“I spent all weekend crying,” Kling said. “You don’t expect to send a kid home on Friday and not see him on Monday.”

Kling added that she doesn’t know how she is going to communicate the horrific news to the other little kids in her class.

The school, Super Kids Learning Center, said in a statement that the whole staff is “in disbelief that we will never get to see his cute little smile or his bright red hair ever again.”

Kling said she is also mourning for Nash’s mother, who had a “very strong” bond with her son. “The first thing I thought about when I heard was his mom,” said Kling, who is the mother of two boys.

Nash’s mother, Nicolette Strauch, a sophomore and employee at OSU, is “devastated by the loss of her two-year-old,” OSU president Burns Hargis said in a statement Sunday.”

The school set up a fund for Strauch, who was one of 47 people injured in the crash.
